There's the romcom bullshit I know and love. Things have gotten just a bit too serious around here.
Regarding who's going to "win" ... jeez, I don't know. If there was a relationship gauge like a dating sim then everyone would be fairly evenly tied, except for Uraka, who has the major doki-dokis for Nariyuki. So at this current juncture, Uraka has the lead. Who knows if one of the other gals will pull ahead in the long run, though.
Also, does anyone have a clue who the left-side gals on the front cover are? Always looking for more cute manga in my life.
EDIT: Found it. [Yuragi-sou no Yuuna-san].
